Cannot set property bufferSource of undefined

[kane-mason]

We were looking through our error logs and found we get a lot of this error:

We are developing games that transition in and out of scenes, loading and unloading new audio so might be a case of refreshing the buffer for a sound that has been unloaded?

Using howler 2.0.8 and have been for probably 2 years

Errors all on iOS

I actually just upgraded to the latest version and have a similar issue, with the below exception :
Exception with thrown value: InvalidStateError: The buffer was already set

and with the debugger pointing to that line :

node.bufferSource = null;
